If you've ever worked in a slaughterhouse or butcher, you'd know how appealing fresh meat can smell. Carving a large piece of beef rump is mouthwatering. I often cook my beef, duck, tuna and lamb rare to get the best flavour.

Those who farm, hunt, work in the food industry are less shy of dead animals. In the modern age there are many who don't know where their food comes from, some even think potato grows on trees. Many have never carved up a chicken even.

Humans and our ancestors have adapted and formed habits over hundreds of thousands of years to survive on many foods. Let us be grateful that we did begin eating meat as it's thought to have been the trigger in our development of tools and larger brains. I find it more remarkable that we ever began eating mushrooms.

It's also worth noting that humans have modified dozens of fruit and veg to our liking through selective breeding. Bananas were not naturally sweet, strawberry were wild strawberry, apples were small and bitter, tomatoes were not of a million shapes and sizes and flavours. Humans have grown these larger, sweeter, and more nutritious and tasty than were found in nature.
